I'm not sure I understand what you mean, Gok. Heaps of toys have been knocked off before being reissued. Metroplex is a recent example. Plus there are heaps of KOs that haven't been reissued yet like the Dinobots, Mirage, Ratbat etc.
EDIT: Okay, now I understand (I'm on 7.2kps dialup at the moment so it took the previous pages of this thread ages to load.) But yes, as I said, Metroplex is a recent example of a KO before a proper reissue.
